multicastLimit
Sets a threshold value on a bridge port that affects the p er-second
forwarding rate of multicast or broadcast traffic that originates on the
segment connected to that port.

Important Considerations
■You can use this command to configure the same setting on m ultiple
ports simultaneously. When you specify multiple port numbers, the
system prompts you to choose the setting and then applies it to all of
the ports.
■A value of zero indicates that no limit is configured.
■If you want to configure a limit for a trunk, be sure to apply it to the
trunk’s anchor port (lowest-numbered port) only. However, be aware
that the limit that you specify applies separately to each link in the
trunk, even though you only enter it once — that is, it is not an
aggregate.
■For a larger array of similar options in the CoreBuilder 3500 and 9000
Layer 3 modules, see the Quality of Service (QoS) chapter in this guide
(Chapter 22) and in the appropriate Implementation Guide.
